DUMP-CAR.

SPECIFICATION forming part of Letters Patent No. 704,578, dated July 15,1902.

Application tiled March 11, 1901.

To @ZZ zultom it may concern:

Be it known that We, EDGAR M. RAY and ROBERT B. MCCONNEY, citizens ofthe United States, residing at Denver, in the county of Arapahoe andState of Colorado, have invented certain new and usefulY Improvements inDump-Cars, of which the following is a specification. Y

This invention relates to that class of cars ro which are adapted tocarry coal, mineral-bearing ores, gravel, sand, and like substances, tothe means by which the holding portion thereof is dumped, and, iinally,to the means by which the holding and dumping mechanr5 isms are held inposition during transportation, all of which Will more fully hereinafterappear. p

The principal object of the invention is to provide a simple,economical, and efficient 2o dump-car.

A further object is to provide a dump-car having a iixed frame withmeans for holding the load in position for transportation and permittingit to be dumped at desired times.

A further object is to provide a dumpingcar having a iixed frame portionwith a holding dumping-box and means for holdingit in looked position,as Will be hereinafter more fully described.

The invention consists, principally, in a dump-car in which there arecombined a fixed frame portion, a body portion vibratingly held therein,and means for holding the dumping body portion in carrying position.

The invention consists, further, in a dumping-car in which there arecombined a fixed frame portion, a dumpingY body portion eX- tendinglongitudinally of the car and swingingly mounted in the frame portion,`and 4o means for looking and holding the dumpingbody in carryingposition.

The invention consists, further, in a dumping-car in which there arecombined a fixed frame portion and tilting dumping-boxes ar- 45 rangedlongitudinally of thercar and open at the outer side, swinging sideshinged to the frame and forming closures for the open side of theholding-boxes, and means for holding the dumping-box portions incarrying posi- 5o tion.

' The invention consists, further and iinally,

sean no. 50.668. (No model in the features, combinations, and details ofconstruction hereinafter described and claimed.

In the art to which -this invention relates it 7o is Well known -thatthe problem ofcarrying broken material-such as coal or mineral-bearingores, gravel, and sand-and delivering it to a desired point ofdestination as economically as possible is one that has long interestedrailroads and users ot railroad-cars.

In the particular class of cars to which this invention rrelates it iswell known that the majority of such cars may be used for the purposeofcarrying materials and dumping 8o them, but that, generally speaking,they are unlitted for the purpose ofl delivering articles, excepting byan automatic dumping process. It is often desirable, however, to havethese cars so arranged that the material 8 5 can be shoveled out of thecars. This is especially the oase in delivering coal or mineral-bearingores in small quantities when it must be discharged by shoveling.

The principal-object, therefore, of our in- 9o vention is to provide acar of the class described Whioh is simple and economical to build andefficient in operation, one that can be used either for the purpose ofautomatically dumping the load or shoveling it out by manual labor, allof which will be appreciated by those skilled in the art.

In illustrating and describing these improvements We have chosen toillustrate and describe them in connection with a peculiar roo type offrame, and have only deemed it necessary to describe so much of a car asis old,

taken in connection with what we consider to be new, as will properlydisclose the invention to others and enable those skilled in the art topractice the same,fleaving out of consideration other and Well-knownparts, which, if illustrated and described herein, would only tend toconfusion, prolixity, and ambiguity.

In constructing a carin accordance with these improvements we make theunderframe of center sills a extending longitudinally of the car andintermediate sills b extending likewise at a point between the sides ofthe car andv the center sills. These sills extend outwardly at each endof the car, as shown in Figs. l and 2, and are tied together at theextreme ends by means of the end sills c and end plates d. To furtherstrengthen the lindert-raming and furnish side stakes or posts for thecar,we provide aplurality of U-shaped T-beams e, which are arrangedtransversely of the car-frame underneath the sill portions abovedescribed and extend upwardly at each side of the car with the iiangedportion of the beam arranged on the inner side, so that thesupporting-sill may rest thereon and the sides of the car be fastenedthereto. These U- shapde metallic members act in a dual capacity-that oftie rods and side stakes or posts. They are secured togetherlongitudinally at their upper ends by means of channel-beams f, whichtie them together in an efficient manner. The web of such channel-beamsis secured to the flanges of the T-beam side posts so that they presenta smooth inner surface to the interior of the car with their fiangesextending outwardly. These channel-beams, which secure the U-shaped T-beams together, may be made in sectionsthat is, they may be made formedof two angle-irons joined together by a Web-plate or may be made of oneintegral channel-beam to suit different circumstances or conditions.The'ends of the car are formed of a steel plate w the entire width anddepth of the body portion. To strengthen the same, end posts g, formedof angle-irons, are provided at each end of the car, secured together bymeans of the horizontal member of the end U-shapecl T-beams and at theirupper ends by means of angle-irons 7i., which also secure them to theupper endsof th'e U -sliaped beams, as shown particularly in Figs. l and3. One side of these end posts may be also secured to the outerAintermediate sills, as shown particularlyin Fig. 3. The portion of thecar above described forms what we prefer to term a fixed frameportion-that is,

such parts are rigidly secured together and the relation at all timesfixed so as to practically support the movable parts and load, ashereinafter more fully described. l

To provide means vby which the load may be carried during transportationand dumped or discharged when the desired destination is reached, weprovide what we term dumping-box portions t', which are substantially'box of it.

L-shaped in cross-section and practically U- shaped in longitudinalsection-that is, the box portion is open at one side and the top, or, inother words, has one side portion, a bottom portion, and two endportions, but is lacking in a top portion and one side portion. Thesedumping-boxes are arranged longitudinally of the car and mounted uponrockshafts j and are formed of a plurality of L- shaped metal T-beamslc, extending transversely of the box and joined together by flat plateswhich form the inner side, two ends, and the bottom portion. Thesedumpingboxes are mounted upon rock-shafts above described, which in turnhave their journal portionsin saddles or brackets t resting upon thesills of the car. A plurality or series of these supporting saddles orbrackets is provided and the square rock-shafts Aare provided withcylindrical journals at the points in which they rotatablyengage withthe brackets. We prefer to provide two or more of these dumping-boxes oneach side of the car arranged longitudinally therewith, so that such carmay be used to carry two or more different kinds of material, and, as inthe case of mineral-bearing ores, carry dierent grades of ore. It willbe understood, however, that the car may be provided with but one ofthese dump portions on each side of the car and extending longitudinallythereof.

It is desirable that some means be provided when the car is in carryingposition to close the outer open side of the dumping-box and also tolock such dumping-box in fixed position to carry the load. In order toaccomplish this result, a swinging door n is provided and pivotallymounted at each side of the car, preferably to the upper fixed portionof the side, so that when it is in its closed position and thedumping-box in` its carrying position, as shown in one-half of Fig. 2,the swinging door completes the closure for the open side andpractically makes a complete To lock this swinging door in position, aswell as to form a seal between the swinging door and the box, and thusprevent leakage of tine material, a hooked lockingplate m is provided,mounted upon a rockshaft o, adjacent to the outer lateral free edge ofthe dumping-box, as shown in Fig. 2. The swinging door is provided witha lip p, adapted to be engaged by the hooked edge 'on thislocking-plate, as shown in Fig. 4.

The rock-shaft of this hooked plate is provided with an operating-handleq and one of the end stakes of the car with a link c, adapted to beslipped down over the free ends of the operating-handle and hold it inits locked position, which also assists in holding the dumping-box inits locked position.

To provide means by which the man ual exertions of the trainman may beused to tilt the dumping-box from a carrying to a dumping position, orvice versa, asegmental geared lever r is provided engaging with ahandwheel s by means of a train of compound IIO gears t, all of whichenables the trainman to tilt such boxes with the least exertionpossible. A pawl n, may be used to engage with one of the spur-gears toassist in holding the dumping-box in locked position.

IVhile we have described ourimprovements with considerable detail as toform, construction, and arrangement, we do not desire to be limitedthereto unduly or any more-than is pointed out in the claims.
